Tottenham Hotspur may need to be in the market for a new centre back this summer, as confusion surrounds the future of star defender Toby Alderweireld.

The 29-year-old looks set to move on this summer given that Spurs can't agree a new contract with the Belgian international centre back, who has been integral to Mauricio Pochettino's side since his 2015 move from Atletico Madrid.

That means that Spurs may need to identify centre backs to target this summer, and one player has allegedly caught Pochettino's eye ahead of the transfer window.

Football.London report that Tottenham want to land Ajax starlet Matthijs de Ligt, but may have to pay around £50million in order to sign the 18-year-old defender this summer.

De Ligt is the latest product of the famed Ajax academy, and he has become arguably the world's top young centre back after starring for the Amsterdam side – and a move to Spurs would hand him a reunion with Davinson Sanchez.

De Ligt and Sanchez played together in the heart of the Ajax back four last season, and Sanchez left the Eredivisie giants in order to join Spurs, with De Ligt now leading the Ajax defence.

Reuniting them could be hugely appealing to Spurs, and De Ligt was even quoted by Soccernews in the Netherlands as saying that Sanchez is 'defensively ruthless', raving about the Colombian's desire to just keep the ball away from the goal, helping De Ligt learn that he doesn't always have to play out from the back.

“Davinson is defensively ruthless,” said De Ligt. “I was someone who wanted to solve every situation by playing football, even by playing to someone in our own penalty area. Now I do not do that anymore. Sometimes you have to kick the ball into the stands. Davinson understood that like no other,” he added.

De Ligt and Sanchez clearly had a strong partnership in the heart of the Ajax defence, and reuniting them could be a masterstroke from manager Pochettino, setting up Spurs defensively for the next 10 years by building around two defenders who already have such a strong rapport – something he already did with Alderweireld and Jan Vertonghen.
